Each adjacent owner is entitled to the lateral and subjacent support which their land receives from the adjoining land, subject to the right of the owner of the adjoining land to make proper and usual excavations on the same for purposes of construction of improvements as provided by law. The permittee is responsible for the prevention of damage to adjacent property and shall not excavate on land sufficiently close to the property line to endanger any adjoining public street, sidewalk, alley or other public or private property prior to supporting and protecting such property from settling, cracking or other damage which may result. [Resolution #1509, 2015; Ordinance #371, 2015; prior code § 7-11-10.]
